LEATHER-MARKING APPARATUS.

Specification of Letters Patent. Patented Aug, 24, 1920,

Application filed October 3, 191.8. Serial o. 256,721.

connected with a leather measuringfma-` chine in such a manner that motion will be transmitted from theV measuring4 wheels or rollers to an indicator or indicator pointer to swingv thelatter over the face of a dial,

and correctly indicate the dimension ascertained by means of the measuring machine, the pointer 'being then closedto close an electrical circuit, and cause a corresponding adjustment ot a set of type carrying wheels Y in such positions that the appropriate types maybe depressed into contactk vwith the leather, or withv the recording strip, by means of a manuallyoperable lever. i

More specifically, it is the objectof my invention to mount a set of type carrying wheels within a suitable cage normally held by a spring, or springs, in a raised position above a suitable bed plate, the lower end of the cage being open and spanned by lan inking ribbon disposed underneath the wheels in the path of the operating types. The

entire cage may be ydepressed by an operat-y ing lever which, during its initial movement,

allows circuits to be connected up` through electro-magnetic devices adapted to controlthe rotation of the wheels,the leversimultaneously releasing a set of wheel operating weights, whereby the wheels may be actuated to the limit of movement permitted by the electro-magnetic mechanism. In this manner, a single manually controlled lever is adapted to utilizey the .indicator pointer, (previously adjusted by the measuringY ma chine), to close an electric circuit, release the. wheel operating weights, and subsequently depress the wheels into vprinting position. y i;

. A is a a series of 4contact points and index marks dial, having face subdivided by' intoy sections and intermediate vfractional sections, each section representing .a unit of measurement, which, for the purpose of this description, may be assumedto be one square foot. VThe fractional units may, for the purpose of this description, be assumed to represent one-quarter, one-half, and three-quarters of a square foot respectively. For convenience of illustration only a few of the l indeX'maiks or contacts will `be indicated on the dial, and these willbe shown on a larger f scale, proportionate to the diameter of the dial, than will the casein actual practice', itY being understood that any desired ployed by merely increasing the size of the dial, and multiplying the contacts and their connections.

A pointer A', mounted to rotate with the number of these contact points may be em- Y vdial supporting arborf a, isadapted lto slide upon said arbor, and is normally supported dial by a spring a coiled Yabout said arbor. The pointer A. is provided with a Contact finger A, adapted Vto enter sockets A in the face of the dial,

the base of each socket being provided with an lelectrode or contact terminakashereinafter described. The sockets in the face of the dial are disposed in such close proximity, and the contour of the intervening walls is such fthat when the pointer is pushed in-V wardly toward the dial against the recoil of the spring' a', the contact iinger A will enter one or another of the sockets, according to the position of the pointer, there being' no intervening ledge of sulifieient breadth to serve as a stop for the movement of the contact finger. y

Motion is transmitted, to 'swing the pointer to a dimension indicating position, from a link B connected with the leather measuring machine. This shaft transmits motion to the pointer throughvthe counterweighted lever B', gear segment B and pinion B, the latter being mounted on the arbor a. When the pointer has been thus adjusted to an indicating position, its contact linger A may be driven intothe opposing lterminal socket in the dial by a su`itable weight C, operating through the hanger rod C', crank pin C", gear wheels D and D',

Y and cam d, the latter being fast upon the shaft d, on which the gear wheel D is mounted. VVhen'theV gear wheel D is thus rotated by a depression of the weight C, cai'n d' pushes against a knob d connected with Vthe pointer'at the aXis about which the pointer swings,and in which knob the arbor bis socketed. The cam therefore pushes the pointer inwardly toward thc dial until the contact linger A is entered in the registering socket.l The pointer will thereupon revmain. in position until the weight C is again raised, whereupon the cam d will bek vretracted, and the pointer will'be pushedout-V wardly by the spring-a.y

Leather measuring-machines are in common use, andit is not deemed necessaryV to illustrate such machine, their structure and mode of operation Ybeing Vwell known in this art. Y. y

,The weight C is released for ar downward Vmovement by means `of a manually operable lever E, this lever having a cam shaped arm (toward the right in Figf1), the inclined'.

E, adapted, when the lever is in normal up-AV right position, to support weight C in the raised position in which it is illustrated in- F ig. l. Vhen the lever is swung forwardly,

surface e ofV thecam shaped lever `armll allows'the weight toslide'downwardly along this surface, the movement'of the weight being thus controlled and made gradual so that it will not jerk upon the crank pin C, and develop uncontrolled momentum in the gear wheels.

Y The 15g/pe wheels ma? the means for cow trollng and operating them.

A series of type wheels are mounted within a suitable cage' or casing F.v VThe units type wheel G contains type muncrals l to, 9 inclusive, in addition to a Zero type. The fraction wheel G also contains `a zero type, and fraction printing types one-quarter, one-half, and three-quarters respectively.V The tens wheel G also contains a Zero type and any desired number'ofr additional number types in serial order7 as on the units wheel. Colled springs g. are adapted tenor,-v

r'nally hold allotl the wheels,with the zero types at the bottom in printing position. above an ink ribbon F', which spans the open lower endv of the casing, and is wound upon -rollers F, whereby when the type wheelsA are depressed to force the ink ribbon into contact with the surface to Abe printed upon, a printing operation will be effected in a'well known manner. V,

The type wheels are actuated from normal position by means of weights H, each con nected with one of the wheels by -a cord H operating lever` E, whereby whenthe operating leverV is in raised position theV weights will'be supported in a raisedl position, and will beV inoperative to aetuatethe type wheels. But when the camarm J is depressed the weights will be released, and'will'f travel downwardly within'the housing. 'The' arrangementis such that if the weight moves downwardly to the limit of,A its 'positive stroke, the type wheel or; number wheel with which itis associated will be turned one completerevolution, and will therefore present the zero type in printing position. This willoccur whenever the lever is depressed to the limit of its swinging'Y movement, unlessl the type wheels are arrested in their rotative movement by the electro-magnetic mechanism now to'be described; and therefore unless the rotation of thel type' wheel is electro-magnetically arrested,'a downward movementof the' wheel carrying'cage will l invariably result in printing VZero marks upon the leather, or any other record `receiving Y Y rests upona cam arm J, connected with the latter, thusfcarrying the type wheels down;

wardly and forcing the types into contact with the 'ink ribbon, andr pressing the 'latter' against the record receiving material'.

'The `rotfative movement of the type wheels iscon'troilled by av set of relatively stationary electro-magnets L concentrically mount merely a ed about the hub of each wheel. Each magnet is provided ,with an armature M provided with av hook M, normally retracted from the rim g of the `type wheel by a spring m. 'But when themagnet L is energized the associated armature M will be swung to bring the hook M into close proX- imity with the rim of the wheel. Thereupon it will be in position to engage a stop catch N mounted on the inner 'face of said rim, thereby arresting the movement of the wheel.V

When the pointer linger A is driven into a socket, as above eXplained, a circuit will be closed through the appropriate magnet, or magnets, in order to arrest the motion of one or more of the wheels in position, with type numerals on the wheels adjusted for printing the pointer on the dial. If the dimension is yfractional dimension, only one magnet will be energized, c., one of the magnets on the fraction wheel Gr). ,But il a whole number dimension is indicated on the dial, which can be represented by a type on the unit wheel G, then one magnet on that wheel will be energized, and if any fractions are indicated by the pointer in addition to said unit number, then one of the electro-magnets on the fraction wheel G will also be energized, this being accomplished by the arrangement of the connections on the switch board, e., the back of the dial), as will now be described.

provided with a series of posts O, numbering i'rom l to 9 inclusive, these posts being each connected with one of the magnets associated with the unit wheel G. Three additional posts P are electrically connected with the three magnets associated with the fraction Vwheel Gr. Other posts Q, equal in number to the number of magnets associated with the tens wheel Gr, are also mounted on the switch board, and electrically connected with such magnets respectively, a iew oil such connections being indicated in Fig. 3.

It will also be observed in Fig. 3 that the terminals `O on the dial which represent unitsare each connected with one of the posts O, and each succeeding fraction terminal P between that unit and the next is electrically connected with one oi the posts P, and with said posts O. Therefore, when the dial pointer registers with the terminal representing two and one-half square feet, or units of measurement, the magnet utilized for positioning the type number 2 on unit wheel G will be energized, and the magnet Y utilized for positioning the one-half type on the fraction wheel will also be energized. Similarly, the dial contacts representing 10 or more are connected with posts Q, alone it' the dimension is in tens, and intermediate dimension contacts, if representing integral the appropriate units posts.

dimensions indicated by the Y are connected with a tens post, and

The intermediate fractional contacts are connected with a tens post, a unit post and a fraction post, thereby controlling the rotative movement ol" all three oi the type carrying wheels. Suitable means for guiding the cage l", and its superposed weight housing, are desirable in order to ause the same to move in a vertical direction. In the drawings I' have illustrateda l'rame S having parallel links S ands, connected with suitable brackets T onthe cage and weight housing.V The frameA 'S extends Yover, the weightv housing, and the 'springs J are connected therewith.
